The Wacker Neuson Washer is a genuine OEM washer designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers. As a factory-sourced component, part is manufactured to the same tolerances and material specifications as the original hardware installed at the time of assembly. This washer fits across the full range of RD27-100 and RD27-120 configurations, including standard and traction control variants, making it a straightforward replacement for machines across multiple serial number ranges.
Key Features
- OEM Material and Dimensional Accuracy — Manufactured to the same thickness, bore diameter, and load-bearing grade as the original hardware, ensuring correct clamping force and surface protection at the fastened joint.
- Drop-In Hardware Replacement — Matches the original seating surface and hole pattern exactly, allowing direct installation without rework or shimming.
- Broad RD27 Series Coverage — Verified fitment across RD27-100 and RD27-120 hydrostatic vibratory rollers, including both standard models and traction control-equipped variants.
- Protects Mating Surfaces — A correctly specified washer distributes fastener load evenly across the joint face, preventing surface deformation, fretting, and fastener loosening under vibration-heavy roller operation.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, ensuring the part number, grade, and finish match what was originally specified for the RD27 tandem roller platform.
A washer serves as a load-distributing interface between a fastener — such as a bolt head or nut — and the surface it clamps against. On a vibratory roller like the RD27 series, mechanical vibration is a constant operating condition, and an undersized or incorrect washer can allow fasteners to work loose, damage housing surfaces, or cause joint failure over time. Using the correct OEM-specified washer ensures the fastener assembly maintains its clamping integrity through the repeated stress cycles that tandem roller operation demands.
